Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communication flow processing method and a terminal.
Background
In the fifth Generation (5G) mobile communication system, or New Radio (NR), the supported operating band is increased to over 6GHz, up to about 100 GHz. The high frequency band has richer idle frequency resources, and can provide higher throughput for data transmission. To achieve the goals of downlink transmission rate of 20Gbps and uplink transmission rate of 10Gbps, MIMO technology with high frequency antennas and larger scale, more antenna ports will be introduced. The wavelength of the high-frequency signal is short, compared with a low-frequency band, more antenna array elements can be arranged on a panel with the same size, a beam with stronger directivity and narrower lobes is formed by using a beam forming technology, and a large-scale (Massive) MIMO (multiple input multiple output) technology uses a large-scale antenna array, so that the utilization efficiency of a system frequency band can be greatly improved, and a larger number of access users can be supported.
In a high-band communication system, since the wavelength of a radio signal is short, it is easy to cause a situation where signal propagation is blocked or the like, and signal propagation is interrupted. If the wireless link reconstruction in the prior art is adopted, the time consumption is long, so a Beam Failure Recovery (BFR) mechanism is introduced, and after a Beam Failure occurs, the terminal triggers a Beam Failure Recovery request process. The terminal sends a beam failure recovery request to the network device side, and the network device feeds back response (response) information of the beam failure recovery request after receiving the beam failure recovery request. For example, the terminal may send a beam failure recovery request through a random access preamble (preamble), and wait to receive feedback information of the network device, such as: a Physical Downlink Control Channel (PDCCH) scheduled by a Cell Radio Network Temporary Identifier (C-RNTI). And after the terminal receives the feedback information of the beam failure recovery request from the network equipment, the terminal judges that the service beam corresponding to the cell is successfully recovered. The feedback information of the Beam Failure Recovery request is transmitted on a specific Control channel Resource configured by the network device, such as a dedicated PDCCH in a Control Resource set (BFR-core) for Beam Failure Recovery.
In addition, the network device may also configure a corresponding spatial relationship, such as a Transmission Configuration Indicator (TCI) State, for a control Channel, such as a PDCCH, and a data Channel, such as a Physical Downlink Shared Channel (PDSCH), of the terminal, where the spatial relationship includes a corresponding Reference Signal, such as a Synchronization Signal Block (SSB) and/or a Channel State Information-Reference Signal (CSI-RS). Further, the network device may also dynamically adjust the spatial relationship between the control channel and the data channel of the terminal, which may also be referred to as changing the corresponding beam.
The terminal triggers a beam failure recovery process when detecting a beam failure event, and needs to switch between different beams when receiving indication information for changing beams sent by the network device. However, when the above processes occur simultaneously, the terminal cannot determine which process is to be processed preferentially, nor can it determine whether the above processes must be completed, that is, when the above two processes of the terminal conflict with each other, the terminal cannot determine how to perform the processing.

Therefore, the conflict solution modes of the terminal side and the network equipment side are unified through the preset processing mode, and the loss of data receiving and sending and the interference caused by the data sending of the terminal on the wrong wave beam are avoided.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the scenario shown in fig. 1, signal transmission is implemented between the network device 01 and the terminal 02 through an antenna beam. Network device 01 and terminal 02 may each include multiple beams, and for example, in fig. 1, it is assumed that network device 01 includes N beams and terminal 02 includes M beams, where N, M are integers greater than 1. N and M may be the same or different, and the application is not limited.
An embodiment of the present invention provides a communication flow processing method, which is applied to a terminal side, and as shown in fig. 2, the method includes the following steps:
step 21: before the beam failure recovery process is finished, if indication information for initiating the beam changing process sent by the network equipment is received, the beam failure recovery process and the beam changing process are processed according to a preset processing mode.
The beam failure recovery procedure referred to in the embodiments of the present invention may be after the beam failure recovery procedure is initiated before the end of the beam failure recovery procedure, but the procedure is not ended. In a high-frequency communication system, since the wavelength of a radio signal is short, signal propagation is easily interrupted due to, for example, blockage of signal propagation. If the wireless link reconstruction in the prior art is adopted, the time is long, and therefore a Beam Failure Recovery (BFR) mechanism is introduced.
Wherein, the beam failure recovery mechanism comprises: the method comprises the steps of beam failure detection, new candidate beam identification, beam failure recovery request sending and receiving beam failure recovery response information fed back by the network equipment. When detecting that the beam fails, the terminal triggers a beam failure recovery process, namely, initiates a beam failure recovery flow, so as to realize beam recovery as soon as possible. Further, the terminal and the network device may support more than one beam, and in order to ensure the system transmission performance, the network device may send instruction information for changing the beam to the terminal, so that the terminal performs information transmission through the beam with better quality. When the terminal detects that the current service beam has beam failure, the terminal initiates a beam failure recovery process, and if the terminal receives indication information for initiating a beam change process sent by the network device before the beam failure recovery process is finished, the terminal can determine the beam failure recovery process and the beam change process according to a preset processing mode so as to avoid data receiving and sending loss caused by process conflict and interference caused by data sending of the terminal on an error beam. It should be noted that the preset processing mode may be predefined, or may be configured by the network device to the terminal.
The communication flow processing method according to the embodiment of the present invention will be further described with reference to different application scenarios.
Scene one, as shown in fig. 3, the method of the embodiment of the present invention includes step 31: after detecting the beam failure event and before sending the beam failure recovery request, the terminal stops the beam failure recovery process if receiving indication information which is sent by the network equipment and used for initiating the beam change process, and executes the beam change process according to the indication information.
In this scenario, a beam failure occurs in the terminal, the terminal initiates a beam failure recovery process for the beam failure, and if the terminal receives indication information for initiating a beam failure recovery process sent by the network device before sending a beam failure recovery request, the terminal may directly stop the beam failure recovery process and change the beam process according to the indication information in order to save power for the terminal.
Scenario two, as shown in fig. 4, the method of the embodiment of the present invention includes step 41: after the terminal sends the beam failure recovery request and before the beam failure recovery process is finished, if the terminal receives indication information sent by the network equipment and used for initiating the beam change process, the terminal executes one of the following steps:
the first method, step 42: and stopping the beam failure recovery process, and executing the beam changing process according to the indication information.
In this scenario, a terminal generates a beam failure, the terminal initiates a beam failure recovery process for the beam failure, and if the terminal transmits a beam failure recovery request but does not receive response information of a network device for the beam failure recovery request, or the beam failure recovery process times out, that is, before the beam failure recovery process ends, the terminal receives indication information for initiating a beam change process, which is transmitted by the network device. The terminal can directly stop the beam failure recovery process and execute the beam changing process according to the indication information, so that the terminal can be switched to the available beam more quickly.
Mode two, step 43: and continuing to execute the beam failure recovery process, and discarding the indication information.
In this scenario, a terminal generates a beam failure, the terminal initiates a beam failure recovery process for the beam failure, and if the terminal transmits a beam failure recovery request but does not receive response information of a network device for the beam failure recovery request, or the beam failure recovery process times out, that is, before the beam failure recovery process ends, the terminal receives indication information for initiating a beam change process, which is transmitted by the network device. The terminal may continue to perform the beam failure recovery procedure and discard the indication information so that the terminal may switch to an available beam through the beam failure recovery procedure.
Optionally, if the terminal stops the beam failure recovery procedure, the terminal may send control information for indicating the beam failure to the network device. The Control information is sent through a Physical Random Access Channel (PRACH), a Physical Uplink Control Channel (PUCCH), a Medium Access Control Element (MAC CE), or a Radio Resource Control (RRC) signaling. That is, when the terminal stops the beam failure recovery procedure and performs the beam change procedure, the terminal may report the beam failure information to the network device, where the act of reporting the beam failure information to the network device includes any combination of one or more of the following: and sending request information on the beam failure recovery resource corresponding to the failed source beam, for example, sending the PRACH on the random access resource corresponding to the beam failure recovery of the source beam. Alternatively, control signaling is sent to inform the network device.
As a preferable example, the control information includes: at least one of beam failure indication information, identification information of a failed beam (which beam failed), bandwidth section BWP identification information corresponding to the failed beam (which BWP the beam failed to occur corresponds to), cell identification information corresponding to the failed beam (which cell the beam failed to occur corresponds to), and measurement result information corresponding to the failed beam (measurement result of the beam failed to occur). Wherein, the measurement results include but are not limited to: at least one of Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference and Noise Ratio (SINR), and the like.
Optionally, the beam failure recovery procedure includes: a contention-based beam failure recovery procedure and/or a non-contention-based beam failure recovery procedure. That is, the terminal may transmit the beam failure recovery request through the contention-based random access resource, or the terminal may transmit the beam failure recovery request through the non-contention-based random access resource.
Optionally, the manner in which the network device sends the indication information for initiating the beam change process may include, but is not limited to: a general PDCCH, such as a dedicated PDCCH in non-BFR-core, and/or a MAC CE.
Preferably, the indication information includes: identification information of the target beam after the beam change. That is, the indication information is used to indicate that the source beam currently failed in the terminal is changed to another target beam, for example, a beam corresponding to the PDCCH and/or PDSCH currently serving is changed, and the indication information carries identification information of the target beam.
Further, the indication information may include, in addition to the identification information of the target beam: identification information of the source beam before the beam change.
Wherein the identification information of the source beam or the target beam comprises at least one of: synchronization signal block SSB identification information (e.g., SSB identification), channel state information reference signal CSI-RS identification information (e.g., CSI-RS identification), and spatial relationship configuration information between beams. The spatial relationship configuration information includes, but is not limited to: transmitting configuration indication information, or Quasi-co-Location (QCL) relationship information. Wherein the quasi co-location relationship indicates that at least one of doppler frequency shift, doppler spread, average delay, delay spread, and spatial reception parameters between different beams is quasi co-located. The indication can be carried out through a quasi co-location Type, wherein the QCL-Type A is used for indicating that Doppler frequency shift, Doppler spread, average time delay and time delay spread are quasi co-location or identical; QCL-Type B is used to indicate that Doppler frequency offset and Doppler spread are quasi co-located or the same; QCL-Type C is used for indicating that Doppler frequency shift and average time delay are quasi co-located or same; QCL-Type D is used to indicate that the spatial receive parameters are quasi co-located or identical.
In the communication flow processing method of the embodiment of the present invention, if the terminal triggers the beam failure recovery process and receives the indication information for initiating the beam change sent by the network device before the beam failure recovery process is finished, the beam failure recovery process and the beam change process are processed according to the preset processing mode, so as to avoid the collision problem between the beam failure recovery process and the beam change process. Therefore, the conflict solution modes of the terminal side and the network equipment side are unified through the preset processing mode, and the loss of data receiving and sending and the interference caused by the data sending of the terminal on the wrong wave beam are avoided.
The foregoing embodiments respectively describe in detail the communication flow processing methods in different scenarios, and the following embodiments further describe the corresponding terminals with reference to the accompanying drawings.
As shown in fig. 5, the terminal 500 according to the embodiment of the present invention can implement details of a method for processing a beam failure recovery procedure and a beam change procedure according to a preset processing manner if receiving indication information sent by a network device to initiate the beam change procedure before the beam failure recovery procedure is ended in the foregoing embodiment, and achieve the same effect, where the terminal 500 specifically includes the following functional modules:
and the processing module is used for processing the beam failure recovery flow and the beam changing flow according to a preset processing mode if receiving indication information which is sent by the network equipment and used for initiating the beam changing flow before the beam failure recovery flow is ended.

and continuing to execute the beam failure recovery process, and discarding the indication information.

Wherein the identification information comprises at least one of:

It is worth pointing out that, if the terminal triggers the beam failure recovery process and receives the indication information for initiating the beam change sent by the network device before the beam failure recovery process is finished, the terminal processes the beam failure recovery process and the beam change process according to the preset processing mode, so as to avoid the collision problem between the beam failure recovery process and the beam change process. Therefore, the conflict solution modes of the terminal side and the network equipment side are unified through the preset processing mode, and the loss of data receiving and sending and the interference caused by the data sending of the terminal on the wrong wave beam are avoided.
